Vortex Sound Research

I want to scale up a v/Oct voltage coming out of my beatstep to do some cv'ing over a keyboard. The problem is that the v/Oct scale is unpractical for the approx 5v range that I need, but I cannot think of a way right now to solve it. The vca's that I have go up to unity multiplication, and even the disting mk4 doesn't hasn't gotten a mode that can give me more than unity gain.

Of course there should be a way I haven't thought of yet, this is modular after all, so that's why I'm asking here
